[Tex/LaTex] Beamer center vertical alignment of two columns

beamercolumnstwo-columnvertical alignment

Given the following MWE:

\documentclass{beamer}

\begin{document}

\begin{frame}
\frametitle{Some title}
\setlength{\leftmargini}{0.5em}
\begin{columns}[c, onlytextwidth]%EVEN SPECIFYING THE c OPTION
    \begin{column}{.5\textwidth}%
        \setlength{\partopsep}{0pt}%AND EVEN REMOVING EXTRA itemize SPACE
        \begin{itemize}
        \itemsep 1.5em
            \item First item bla bla bla bla some more text
            \item second item bla bla bla bla some more text bla bla
            \item third item bla bla bla bla some more text bla bla bla bla bla bla
        \end{itemize}
    \end{column}%
    \begin{column}{.45\textwidth}
        \includegraphics[width=\textwidth, height=5.5cm]{example-image}
    \end{column}%
\end{columns}

\end{frame}

\end{document}

Is it me or the two columns do not align properly? It seems there are more space left on the top of the image (noted in red) than on the bottom (in black)… Note as well that I added the following line, as indicated here…

\setlength{\partopsep}{0pt}%

fig

Any idea?

It seems itemize inserts some spacing above the environment, just as center does. A fix for the example you've provided is to put the figure in a center environment. 

\documentclass{beamer}
\begin{document}
\begin{frame}
\frametitle{Some title}
\setlength{\leftmargini}{0.5em}
\begin{columns}[c, onlytextwidth]%EVEN SPECIFYING THE c OPTION
    \begin{column}{.5\textwidth}%
        \setlength{\partopsep}{0pt}%AND EVEN REMOVING EXTRA itemize SPACE
        \begin{itemize}
        \itemsep 1.5em
            \item First item bla bla bla bla some more text
            \item second item bla bla bla bla some more text bla bla
            \item third item bla bla bla bla some more text bla bla bla bla bla bla
        \end{itemize}
    \end{column}%
    \begin{column}{.45\textwidth}
    \begin{center}
        \includegraphics[width=\textwidth, height=5.5cm]{example-image}
    \end{center}
    \end{column}%
\end{columns}
\end{frame}
\end{document}
